This invention relates to'hose nozzles and` the like, and has for anobject to provide ya nozzle of improved and simpliiied constructionwhich is adapted to be quickly and easily adjusted for producing arelatively small stream or spray, or a comparatively large stream o`rspray substantially equal to the-full capacity of the conduit supplyingthe liquid. Another object is to provide an improved nozzle having' aplurality of valves, and acommon operating member for successivelyopening or clos-ing the respective valves. It consists in certainfeatures and elements of construction herein shown and described, asindicated by the claims;

In the construction illustrated in the drawing, the nozzle ttingincludes a coupling member,- 10, which is interiorly threaded at one endfor connection with the usual coupling member of a. hose or the threadedend of any suitable form of conduit. This coupling member is providedwith a' reduced tubular extension 11, on the outer end of Which-anoperating sleeve, 12, is threaded and arranged for lrotativeaxialmovementthereon, which movement controls two concentricallyarranged valves located adjacent the outer end of said sleeve,- 'asyhereinafter described. Preferably cast integral with the interior of theextension, 11,- is a spider, 14, with which is rigidly associated acentrallyv disposed needle valve member, 135, which is herein shown as aseparate element having itsrear end riveted over as indicated at 15a',in said spider.` As may be seen in Figure 1 of the drawing, this needlevalve element extends lfor convenience,

lmember for the outer 1930;A serial No. 460,808.v

a substantially distance beyond the outer end of the tubular" extension,11, and has its eX- treme end conicallyriorme'd as indicatedat 16, whichserves as the valveproper.l Slidably mounted on the outer endof saidneedle valvemember is a part, 18, disposed wholly within theoperatingsleeve, 12, and which, may be termed af duplex valveelement becauseV itSielves as a seat for the inner valve and -is ineiiect the valve properfor the outer valve, as will hereinafter' be seen.`

j The duplexvalve element includes a sleeve, 19, which Vfits' snuglyaround and is axially movable on the needle valve'member, and` Wli'chsleeve is provided with a pair of diametrically opposite longitudinallyextending slots, through which extends a" cross pin, 21, projectingdiametrically through the needle valve element. The pin and slots thusprevent rotation of saidv cduplex7 element on the, needle valve memberand serve to define the limits of axial movement of said fduplex elementrelative' thereto. `Integrally formed withthe sleeve, p19, of the duplexelement. is an annular portion, `22, the inner surface ot which, asindicated atp23`, serves as the seat for the conical valve, 16, whichcontrols the inner valve port or orifice, 23a, in said dir plex element,while the exterior surface of said portion, 22, .is formedrusto-conically, as indicated at 24, and serves" as the valve orsupplementary rt'ion, 22, and the duplex element are con` 8 ality oflongitudinally' exwhich Vare radially offset relative to said needlevalve member, 15, as seen in Figures 3 and 4', so as to insure passageof the liquid'therebetween for discharge through the central orifice,23e,x in the annularporti-on, 22. Y l

To furtherfinsure true axial movement of thiSjFduplex element I formsaid element with a plurality of' radially extending fins, .95 26,Vwhichare* dimensioned to substantially engage the inner wall of theoperating sleeve, Y 12, and preferably these fins v.arelocated inalignment withv4 the respective ribs, 25, so as to reduce theObstruction to the flow of the p valve.

' element outer end of the operating sleeve, as may be clearly seen inFigure`4, and 1s arranged to abut and firmly lock the seat, 29, inposition 'against said shoulder, `28, of the operating sleeve. The seat,29, may be made of any suitable material such as metal, fibre, rubber,

etc. Preferably it is held against rotation with respect to saidoperating sleeve, and to so maintain said seat, it is formed with one ormore laterally projecting lugs, 33, vwhich are adapted to register incorrespondingly formed slots, 34, providedin thestop shoul-v der, 28. Byvirtue of this construction -it will be apparent that may be'quickly andreadily replaced i'f-necessary when it becomes worn or mutilated merelyupon the removal of the retainer-'niember, 32. The duplex element isnormally yieldingly urged in an outward direction, tending to maintainits valve, 24, 1n engagement with its cooperating seat, 30, inv thesleeve, 12, by means of a coil spring, 86, circumscribing the rear endof the needle valve member and reacting between the spider, 14,

and a washer element, 3T, disposed against the end of the sleeve, 19, ofthe duplex element; Thus when the operating sleeve, 12, is threaded ontothe coupling extension, element by reason of the contact of its valve,24,7with the seat, 30, is Vgradually moved rearwardly along the needlevalve member until the seat, 23, of the duplex element is `broughttightly in contact with the conical valve proper, 16,

of the needle valve member, in which position the spring, 36, is undersubstantial compression. It will now be apparent that when the operatingsleeve, 12, ly, or outwardly with respect to the extension, 11, of thecoupling, the springwill tend to hold the valve, 24, of the duplexelement tightly against its seat, 30, in theend of the operating sleeve,12, through a limited range of axial movementof said operating sleeve,determined by said cross pin, 21, and slots, 20,v and afforded by thethreaded connection of said sleeve on the coupling eXtension. Suchmovement of the operating sleeve gradually shifts the seat, 23, of theduplex i away' from its cooperating c one, 16, of the needle valvemember,'15, so as'to permit a flow of the liquid through the innercontrolled thereby, either this valve seat element, 29,

is rotated opposite-v Lacasse i axially shifted outwardly to the` extentthat the duplex element is moved to its outermost limit by the spring,86, as determined by the-length of its slots,v20, then upon furtherrotation ofthe operating sleeve in the same direction the outer seat,29, will be gradually moved away from the valve, 24, of the? duplexelement, thereby opening the outer or supplementary valve port, 29a,which provides a substantially increased flow, approximately'.equivalentto the full capacity capable of being discharged through the eX-tcnsion, 11, of the coupling. AThe two valves arethus opened insuccessive order, and obviously when vthe operating sleeve, 12, isrotated inwardly after said valves have both attained their full openposition, the outermost valve will be first closed,-that is, the seat,29, will first be broughtv into contact with the valve, 24, oftheduplex7 element, closing the orifice, 29a; and continued rotationwillcause the duplex element to be gradually moved rearwardly on themember, 15, compressing the spring, 36, and gradually moving the seat,23, of the duplex element toward its cooperating cone valve, 16, von theend of the needle valve member for closing theY orifice, 23, of theinner valve.

As is generally understood, in valves of this character when Ythe valveis just cracked7 off of its seat the flow of the liquid through theorifice controlled by the valve seat is caused to take the form of aspray and as the effective valve opening is increased, the spraygradually takes the form of a concentrated stream. Thus by thisconstruction the innervalve member may produce either a relatively smallstream or spray and when it is desired tohave a greatly increased flowor capacity the outer valve may then be opened in addition. To insureobtaining a relatively wide sprayvvhenl the outer valve is in apartially open position, l. preferably form the annular portion, 22,beyond the valve,24,` of the duplexl7 element with a reversely curvedannular bead, 38, which serves to deflect the liquid in a manner tocause a Wide conical spray; the shapeV of the exterior surface of theseat, 29, and the Aretaining member, 32, being properly designed so asto assist in this result also. In Figure 4, the duplex element is shownat a position corresponding to substantially maximum opening of theouter lll) valve, which will .produce a relatively concentrated largecapacity stream.

To insure against leakage between the threaded connection of theextension, 11, and the operating sleeve, l2, I preferably provide asuitable packing element 40, adjacent the rear end of saidoperating'sleeve and which is tightly held in pla-ce by a packing ring,4l, threaded onto the rear end of the said sleeve, as shown in Figure l.y

Although I have shown and described a preferred embodiment of myinvention, it will be understood that the construction and arrangementof parts may be varied without departing from the spirit and scopethereof. I therefore do not wish to be understood as limiting myself tothe particular construction illustrated, except as indicated in theappended claims.
